A-10 Warthog The mean machine; the A-10 arrived at Oshkosh. The A-10 Warthog is primarily a low-altitude, close air support aircraft best known for its nose mounted 30mm gatling gun designed to fire armor-piercing depleted uranium and high explosive incendiary rounds. Its single-seat cockpit forward of the wings with a large bubble canopy provides the pilot with all-around vision. The pilot and part of the flight-control system are protected by titanium armor while manual systems back up their hydraulic flight-control systems. The self-sealing fuel tanks also have internal and external foam protection.
